DISPENSER FOR OIL CANS -Fi1d Dec. 2, 1953 ATTQRNEYS Patented Jan. 7, 1936 UNITED STATES PATENT OFFICE 7 Claims.

The present invention relates in general to liquid dispensers and more particularly to an oil dispenser adapted to receive and open filled oil containers of a special shape or contour conforming to the shape or contour of the dispenser body.

Oil dispensers now on the market for opening lubricating oil containers and dispensing their contents take filled oil containers of the proper size indiscriminately without regard to a specific :brand or origin. The dispenser of the present invention, on the other hand, is adapted to receive, open and dispense the contents of only a special type of oil can representing a certain brand of quality oil. This restriction is a desirable restriction and works in favor of the ultimate consumer who is assured of the brand of quality oil he asks and pays for and also works in favor of the refiner, or distributor who is assured that only his brand of oil can be dispensed in the dispenser of the present invention.

An important object of the present invention, therefore, is the provision of a combination oil dispenser and oil container, each having a shape or contour or connection elements complementary of the other so that the combination of. the two will substantially prevent the dispensing of competing or inferior oils in the dispenser of the present invention.

Another object of the invention is the provision of an oil dispenser which may be of standard manufacture, made by present equipment, except that by a simple additional operation its body may be provided with certain connecting or key members which will substantially prevent the admission into the dispenser of a filled oil container which has not been provided with a complementary or counterpart connecting or key member.

Another object of the invention is the provision of an oil container which may be of standard manufacture, made by present equipment, except that by a simple additional operation it may be provided with certain connecting or key members which will prevent its insertion into a dispenser which has not been provided with complementary or counterpart connecting or key members.

Numerous other objects-and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawing, discloses a preferred embodiment thereof.

Referring to the drawing:

Figure l is a side elevational view of a container and dispenser combination embodying the present invention, dispenser parts being broken away to. more clearly show details of construction;

Fig. 2 is a sectional plan view taken at 22 in Fig. 1 to show a projecting rib and indent combination formed in the container wall; 5

Fig. 3 is a top plan View, partially in horizontal section, of the dispenser takenat 3-3 in Fig. 1 to show the dispenser body having a wall contour which is the counterpart of the container wall shown in Fig. 2; and Fig. 4 is a similar View taken of both dispenser and container, the latter being illustrated in section, showing how the complementary shaped container wall keys into its counterpart in the dispenser body.

Referring in more detail to the drawing, a preferred embodiment of the present invention comprises a container A and a dispenser B. The container A comprises a body H having top and bottom endslZ and I3 double seamed or other- 20 wise suitably secured thereto.- These standard parts of the container A may be made and assembled with present equipment. By an additional operation or operations, an indent (or indents) l5 and a projecting bead or rib (or ribs) I6 are formed in the container body and end seam adjacent either or both ends of the container A. These indents l5and outwardly project'mg ribs I 6 may extend upwardly or downwardlya short distance from either of the body ends or they may run longitudinally of the container throughout its whole length.

The dispenser B comprises a body or holder ll of a size and shape corresponding to the size and shape of the oil containers A to be opened therein. The body or holder i1 terminates in an outwardly curledrounded top l8 and at the opposite end is an outwardly curled bottom rim IQ. It is closed adjacent its lower extremity by a conical shaped bottom 2!, and a tubular outlet part 22 of the latter has secured to it, by soldering or welding, 21. flexible dispensing tube or hose 23, which terminates in a delivery nozzle 24. The tube and nozzle 2324 may be held in'upright or non-dispensing position, as shown in Fig. 1, by hooking the slightly curved end of the nozzle 24 in a hooked bracket 25 attached to the top rim of the dispenser B.

A knife or cutter device 26 of any desired form, but preferably of the type shown in Fig. 1, is positioned within the body I! of the dispenser B and is secured to the inner wall of the body by means of screws 21 or in any other suitable manner. It is preferably positioned relative to the top and bottom of the dispenser B so that 55 the upper end 28 of the cutter is within the top edge l8 and the lower end or supporting ring or band 29 is spaced from the conical bottom 2| a distance sufiicient to permit a whole unit charge of oil to be held between the parts 2| and 29 without touching or soiling the container.

A handle 3|, for holding or carrying the dispenser B, is secured to the dispenser body I! by means of welding the terminal flanges of the handle brackets upon the body I! preferably opposite the hooked bracket 25.

In order to substantially prevent the admission or insertion into the dispenser B of a filled oil container which has not been provided with a complementary or counterpart connecting or key member (or members), the dispenser B is also formed with an indent (or indents) 32 and a projecting bead or rib (or ribs) 33 corresponding with the counterparts I5l6 of the oil container A and extending longitudinally of the dispenser body from the top I8 to the upper edge of the supporting ring or band 29, which also serves as a stop for the container B.

From the foregoing description it will be obvious that in the opening and dispensing operation the container B is grasped by the operator at its top and inserted into the top of the dispenser B with the parts I5--|6 of the container in alignment or registry with the parts 32-33 of the dispenser and pressed down upon the knife or cutter 26 until the bottom edge l3 of the container engages the upper edge of the stop 29. A substantial opening will be produced in the bottom wall of the container and the oil contained therein will be dumped or cascaded quickly and completely (excepting a few drops which cling to the inner surface of the container) into the space defined by the parts 2I29 of the dispenser and may be held there or dispensed at will through the parts 22-23-24 into any desired place of deposit, such as the crank case of an automobile.

It is though that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form herein before described being merely a preferred embodiment thereof.
